Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126206, here are decompositions:

7 + 126199 = 126206
79 + 126127 = 126206
109 + 126097 = 126206
127 + 126079 = 126206
139 + 126067 = 126206
193 + 126013 = 126206
277 + 125929 = 126206
307 + 125899 = 126206

Showing the first eight; more decompositions exist.
